The last line here is a bit disingenuous. We aren't expecting anything about `register_page`'s return value. Please change this back to the style it was before:
```ruby
it "finds or create the namespace and register the page to it" do
  namespace = double
  expect(application).to receive(:namespace).with("public").and_return namespace
  expect(namespace).to receive(:register_page).with("My Page", {:namespace => "public"})

  application.register_page("My Page", :namespace => "public")
end
